Chopping-type stalk returning-to-field machine

Abstract

The invention relates to a stalk returning-to-field machine, in particular to a chopping-type stalk returning-to-field machine, which comprises a power transmission mechanism, a rack and a main shaft which is arranged on the rack. The main shaft is fixedly arranged on the rack through bearings. Two reverse crankshafts are arranged on the main shaft and are respectively connected with cutter rods and cutters at the lower parts of the cutter rods through shaft sleeves. A pull rod is arranged at the back of each cutter. The front end of each pull rod is hinged onto the cutter or the cutter rod. The rear end of each pull rod is hinged onto the rack. Further, roll stands are additionally arranged at the front lower part of the rack. A transverse press roll is arranged on the roll stand. The chopping-type stalk returning-to-field machine has the beneficial effects that 1) since corn stalks are chopped into short sections, the retention of nutrients is facilitated; 2) the soil of a chopped plot is comparatively loose, the soil moisture conservation effect of a dry land is good, the air drying of the ground surface of a wet land is facilitated, and the cultivation of crops is facilitated; 3) sine the stalks are chopped into short sections, the short stalk sections can be conveniently buried through plowing by using a plow; 4) and compared with the transitional crushing-type stalk returning-to-field machine, the power consumption is less and the operation efficiency is high; and according to tests, the cost of returning the stalks is only 3-15 Yuan per mu.

Description

Technical field [0001] The invention relates to agricultural machinery, and further is a straw returning machine, especially a straw returning machine made by the principle of shredding. Background technique [0002] At present, after crops are harvested, it is especially necessary to return corn stalks to the field, which not only enables energy reuse, but also ensures the fertility of the soil, and at the same time avoids environmental pollution caused by burning stalks. Therefore, people have invented many kinds of straw returning machines. Most of these equipment use straw crushing devices. This kind of device is complicated to manufacture, requires high power to cooperate with, consumes large power, and has unsatisfactory work efficiency; parts wear out quickly and maintenance costs are high; Straws have high toughness. The crushed straws are mostly in the shape of lotus roots and broken filaments. The crushing quality is poor. The ground is like a carpet, which is not condu...

Problems solved by technology

Therefore, people have invented many kinds of straw returning machines. Most of these devices use straw crushing devices. This kind of device is complicated to manufacture, and the power requirement for it is high, the power consumption is large, and the work efficiency is not ideal; the parts wear quickly and the maintenance cost is high; Straw has great toughness, and the crushed straw on the surface is mostly in the shape of broken lotus roots, and the crushing quality is poor. The ground is like a carpet, which is not conducive to the soil to absorb sunlight; The sowing operation is difficult; its pulverization speeds up the air-drying of the straw and the loss of nutrients, which greatly reduces the nutrient utilization of the straw; and the operation cost is high. After testing, it takes 30-60 yuan to return 1 mu of land
